F4i HID connection problems

Yes. An engine in good health will have nice copper brown plugs. Yours are a bit sooty meaning rich fueling mixture. But I am more worried by the oil residue I see on them. Did they have oil on them or the camera flash is confusing me? You have reams of internet pages written on how to read spark plugs(don't have to be motorcycle specific), look them up.
